1.1 Introduction

1.1.1 Historical Approach to Organic Semiconductors

Organic semiconductors have the potential to be used in future electronic devices requiring structural flexibility and large‐area coverage that can be fabricated by low‐cost printing processes. Ordinary organic materials such as plastics (polyethylene) have primarily been regarded as typical electrical insulators. However, graphite exhibits the high electrical conductivity [1], which has been attributed to their molecular structures, which are made of network planes of the conjugated double ...
